Gold for lightweight men while O'Donovan brothers miss out
Mark O'Donovan and Shane O'Driscoll claimed gold and Denise Walsh landed silver at the World Cup in Belgrade but Olympic silver medallists Gary and Paul O'Donovan had to settle for fourth place.
This was the first of three World Cup events, with the overall winners being crowned after further regattas in Poland and Switzerland over the next two months.
O'Donovan and O'Driscoll were first home in the lightweight men's pair, leading from before halfway to beat a small field of four boats in a time of 6:46.650. Russia were second, with Great Britain third.
The Skibbereen crew - neck and neck with Joel Cassells and Sam Scrimgeour of Great Britain for the majority of the race - produced a big sprint in the final 500 metres to claim gold.
Walsh, also from Skibbereen, produced a big finish to take second place in the lightweight women's single sculls.
She clocked 7:56.240, just under four seconds behind Swiss winner Patricia Merz.
Gary and Paul O'Donovan finished the lightweight men's double sculls final in 6:27.120, just a second and a half behind winners Peter Chambers and Will Fletcher of Great Britain and half a second behind the Polish pair in third.
Sanita Puspure took fifth place in the women's single sculls final, having qualified via the repechage.
